description
logic diagram (positive logic)
The SN65076B and SN75076B differential bus
transceivers are monolithic integrated circuits
designed for bidirectional data communication on
multipoint bus transmission lines. They are
designed for noisy environments, where a
low-impedance termination to ground is required.

The SN65076B and SN75076B combine a differential line driver and a differential input line receiver, both of
which operate from a single 5-V power supply. The receiver has an active-low enable. The driver differential
outputs and the receiver differential inputs are connected internally to form differential input/output (I/O) bus
ports that are designed to offer minimum loading to the bus whenever the driver is disabled or
VCC = 0. These ports feature wide positive and negative common-mode voltage ranges making the device
suitable for party-line applications.
